T0 @ZZ whom t mag concern.-

Be it known that we, HENRY WILDE and THOMAS Oosenovn, citizens of theUnited States, residing at New London, in the county of-New London andState of Connecticut, have invented a new and useful Bobbin or Quillfinding Machine, of which the following is a specification.

This invention relates to improvements in machines for winding bobbinsand quills, and is designed more especially for use in connection withthe winding of iiner grades of silk and other yarns where undue strainand friction cause frequent breakage during the winding operation.

A further object of the invention is to construct a winding-machine inwhich the bobbin or quill holder is automatically adjusted to presentsuccessively fresh winding-surfaces as the winding operation progressesand, further, to provide a winding-machine in which the bobbin or quillis held on a non-revoluble support that is adjusted longitudinally,receiving a step-by-step movement during the winding operation.

A still further object of the invention is to construct awinding-machine in which the winding operation will be automaticallystopped when the bobbin or quill is full.

A still further object of the invention is to construct awinding-machine including a hollow revoluble spindle into which thebobbin or quill enters, the latter being moved vertically by thetraverse-rail while the spindle is held from longitudinal movement.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in the novel construction and arrangementof parts hereinafter described, illustrated in the accompanyingdrawings, and particularly pointed out in the appended claims, it beingunderstood that various changes in the form, proportions, size, andminor details lof the structure may be made without departing from thespirit or sacriiicing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is an end elevation of a portionof a windingmachine constructed in accordance with the invention. Fig. 2is a side elevation of a portion of the frame. Fig. 3 is a view of anumber of the parts shown in Fig. 2, drawn to an enlarged scale. Fig. 4is a transverse sectional elevation of one of the spindles. Fig.

5 is a plan View of the same. Fig. 6 is a detail sectional plan view ofthe belt-shifter and its support. Fig. 7 is a rear elevation of aportion of the traverse-rail together with the `bobbin-holder.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

In the drawings there is shown a portion of a winding-machine includingan end frame 1, a spindle-rail 2, and a traverse bar or rail 3.

The end frames have bearings for the reception of ahorizontally-disposed shaft 4, carrying a number of shafts 5, over whichextend driving-bands 6 to the several spindles, or the usual drum may beemployed, if desired. At one or both ends of the shaft 4 are pinions 8,intermeshing with gears 9, and each of said gears is mounted on ashortshaft 10, adapted to a bearing in the end frame, the opposite end of theshaft at the outer side of the frame carrying a pinion 11, whichintermeshes with two gears 12, that are mounted on stud-shafts 13. Thepinions 12 have elongated hub portions 14, carrying cams 15, againstwhich bear pins or antifriction-rollers 16, carried by the inner ends ofa pair of rock-levers 17, that are pivotally mounted on studs 18,projecting from the frame.

In the upper portion of the frame are bearings for the support of a pairof horizontallydisposed traverse-rail rock-shafts 19, having rocker-arms20, that are connected by links 21 to the rock-levers 17, and saidrock-shafts 19 will receive an oscillatory movement at each revolutionof the cams 15. On the spindlerail are arranged standards 23, which alsoeX- tend through guiding-bolts near the ends of the traverse rail, andon each standard is mounted an elongated lower sleeve 24, above whichisa second sleeve 25, although the two lsleeves may be formed integral,if desired.

The lower end of the sleeve 24 has an enlarged collar or Harige 26,which rests on a forked arm 27, projecting from the rock-shaft 19, andthe movement of the rock-shaft is thus transformed into a verticalmovement, the traverse-rail being raised and lowered any desireddistance in accordance with the character of the bobbins or-quills beingwound, and this may be adjusted byproviding the rocklever 17 androcker-arms 20 with slots in order that the point of connection of thelinks 21 may be made at a greater or less distance from the fulcrums ofsaid members, and thus alter the throw.

In each traverse-rail is an opening for the reception of the lower endof a hollow standard 29, through which extends a rod 30, that may beformed of round wire of proper diameter, the rear face of the rod beingprovided with ratchet-teeth 31, with which may engage a spring-pawl 32,the opposite end of which extends through a suitable opening in thehollow standard. The spring-pawl has a forwardly-extending portionruiming through a guide-opening in the traverse-rail and terminating atthe point of the rail in a pushbutton 34, which may be forced in for thepurpose of disengaging the pointed end of the pawl from the rack-teeth,and thus permit the moving of the rod 30. The rod receives astep-by-step upward movement during the operation of the machine and islocked in each new position by the pawl. f

1n the spindle-rail are bearings for the reception of spindles 40, theshank portions of said spindles extending through the rail, and theirupper heads, which are preferably in the form of inverted cones, restabove the top of the spindle-rail. At the lower end of the spindle-shankare arranged a loose pulley 41 and a fast pulley 42, the loose pulleybeing uppermost, and driving-band 6 may extend around either of thesepulleys, running idly with the loose pulley after the bobbin has beenwound.

At a point adjacent to each of the spindles and guided in suitableopening in the spindlerail is a vertical guide-rod 47, the upper end ofwhich is bent at a right angle and is provided with an eye 48, throughwhich extends the rod 30, and the lower end of the rod 47 rests on aspring-pressed pivotally-mounted belt-shifter 49. Thebelt-shifter 49 issubstantially in the form of a bell-crank lever, its apis on the surfaceof the fast pulley 42. /VhenV the winding of the bobbin has beencompleted, the top of the bobbin will engage against the eye 48 andraise the rod until its lower end is clear of the shoulder 52, afterwhich the spring 50 is free to turn the shoulder on its fulcrum untilthe shoulder 53 engages against the end of the rod, and during thismovement the driving-band will be shifted from the fast pulley 42 toloose pulley 41. In order to permit of the manual adjustment of theshifter at the commencement of the winding operation, each of suchshifters is provided with a thumbpiece 54, which may be grasped by thespinner and turned to shift the band back to the fast pulley 42, butexcessive movement is prevented by a shoulder or arm 55, which forms apart of said shifter.

Each spindle 40 is hollow for its entire length, the lower portion ofthe bore being approximately cylindrical, while near the upper portionit is slightly tapering and at the top is enlarged to form a circularchamber 57, in which is placed a ring 58, that may be formed ofvulcanized fiber or of metal, and said ring is grooved at its lower edgeto form a ball-race for the reception of an annular row of bearingballs59, that rest on a ball-rest formed bythe wall of the chamber 57. rIheinternal bore of the ring 58 is tapered to correspond to the taperingwinding of the bobbin or quill, andv said ring is confined in place bymeans of a holding-ring 60, that is secured' to the top of the spindle.although no clamping or binding action will be exercised and the ringmay be at any time freely held from movement while the spindle continuesto revolve.

Extending at an oblique angle to the main bore of the spindle andcommunicating therewith is a thread-passage 62, at the upper end ofwhich is an eye 63, formed of porcelain or other like material, in orderto keep the thread from contact with the metal, and the thread or othermaterial to be wound passes up from the spool or spools on thespool-rail up through the hollow spindle and eye and is thence woundupon the bobbin.

In the operation of the device a bobbin is secured on the tapering endof the bobbinholding rod 30, and the bobbin and rod are lowered untilthe bobbin is within the ring 58 and in contact therewith. The windingoperation is then started, the spindle rotating rapidly around thebobbin and winding the thread or yarn thereon. During the windingoperation the traverse-rail is raised and lowered, and the accumulatedyarn will again cause the bobbin to make contact with the ring 58 duringthe downstroke of the traverse-rail. The traverse-rail, however, iscontinuing its downward movement while the bobbin and rod remainstationary. This causes the springpawl to click over one or more teethon the rod 80, and the traverse-rail in again elevating the bobbin willmove to a somewhat higher point than before. This operation willcontinue, andas often as thread accumulates in suflcient quantity tostop the bobbin by contact with the ring 58 the bobbin will be raisedhigher and higher until finally its upper end comes into contact withthe ring 48 and raises rod 47 to permit the changing of the belt or bandfrom the fast pulley to the loose pulley through the operation of theshifter, and this stops the operation. The spinner will then raise thebobbin further and after removing the filled bobbin will put a new onein place and then after first forcing back the pushbutton 34 will lowerthe rod 80 and bobbin until the latter is in Contact with the ring 58.The shifter 49 is then turned by means oi' the thumb-piece 54 and thebobhin is shifted to the fast pulley 42, the operation continuing asbefore.

The machine constructed in the manner described may be run at a veryhigh rate of speed, and owing to the fact that it contains butcomparatively few parts will need but very little repair or adjustment.

Having thus described the invention, what is claimed isl. In windingmachinery, arevoluble winding member, a bobbin-carrier, means operablethrough the thread or yarn on the bobbin for imparting progressivestep-by-step movement to the bobbin-carrier in the direction of itslength, and means for locking said bobbincarrier in the position aftereach movement.
